Great experience, fantastic driver and guide - Had a great time on this trip, enjoyed visiting some stunning locations. The driver (Vladimir, I think) had a great sense of humour and really added to the experience with the information he gave us. Would recommend!

Easy way to get a must-see Slovenia experience - If you are going to Slovenia for the first time, you've got to make time to see Postojna Cave, one of the main tourism attractions in the country. It's a very cool place and something that should be on everyone's checklist. Predjama is a nice addition to the tour with dramatic view and an interesting backstory. This tour gave us a nicely paced look at both these places with a friendly English-language guide.

Stop searching and just book it! - We saw the caves on The Amazing Race and put it on our bucket list. We did the Postojna Cave & Predjama Castle Tour. The caves were everything we expected but the castle? Wow, just WOW! One of the best castles we have ever seen in Europe. The audio guide brought the whole experience to life. To Do in Slovenia has the perfect mix - a knowledgeable tour guide and plenty of time to roam around on your own. Book them for all your Slovenian tours! They responded quickly to any questions we had.

A Day I Will Never Forget - Incredible views, great knowledgeable host and enjoyed small group. The cave was out of this world in beauty, and our English speaking guide gave us valuable instruction. Predjama castle was breathtaking as well. Perfect day! I highly recommend booking this trip.

Spectacular tour - Caves of afterlife leave you breathless for the wonder of stalactites and stalagmites inside. Lovely. An electric train takes you to the starting point and a Guide explains everything. Excellent and beautiful. The castle is also one of the most beautiful castles I have ever visited, well maintained and preserved. Really a gem. The price of the ticket may seem high at first but believe me, it is worth it.

Castle not; Cave a big yes! - Make sure you choose the early version (8:00 a.m.). The traffic in the afternoon greatly reduced our time at the castle. The Postojna Cave tour was awesome. As far as castles go, we got more out of our visit to the Ljubljana castle. Ljubljana was one of our favorite stops on the trip.

Fab experiences, not enough time - Great attractions but not nearly enough time given to enjoy everything. The tour guide was great but we felt rushed, especially at the castle where we were unable to see everything.
